Megjegyzések:	Change of avian migratory behavior is one of the best-studied phenomena presumably associated with contemporary climate change, yet to what degree these behavioral changes represent responses to climate warming is still controversial. We investigated interspecific variation in migratory behavior over three decades at a Central-European site, testing whether the type and extent of behavioral change are predicted by species' responsiveness to short-term variation in large-scale climatic indices. We found that species with earlier arrivals at the breeding grounds after winters with higher North-Atlantic Oscillation indices were more likely to overwinter at the study site. This behavior was more frequent in the second half than in the first half of the study, although the extent of this change was not predicted quantitatively by short-term climatic responsiveness. Overwintering was more prevalent in short-distance migrants with more complex diets and larger population sizes. Furthermore, species arriving earlier after summers with higher Sahel rainfall indices increasingly advanced their first arrival date, whereas species that do not molt in the pre-breeding season increased their frequency of overwintering in more recent years. Our results demonstrate that interspecific variation in short-term climatic responsiveness predicts long-term changes in migratory behaviors, supporting that the latter are responses to climate change. Furthermore, the type of response (advancing arrivals or overwintering near the breeding grounds) depends on life history. Finally, we found that overwintering behavior during the study period predicted subsequent trends in population size, suggesting that information on temporal changes in migratory strategy may help conservation planning and risk assessment.

Megjegyzések:	Trait-based approaches are widely used in community ecology and invasion biology to unravel underlying mechanisms of vegetaton dynamics. Although fundamental tradeo ffs between specifc traits and invasibility are well described among terrestrial plants, litle is known about their role and functon in aquatc plant species. In this study, we examine the functonal di fferences of aquatc alien and natve plants statng that alien and natve species di ffer in selected leaf traits. Our investgaton is based on 60 taxa (21 alien and 39 natve) collected from 22 freshwater units of Hungarian and Italian lowlands and highlands. Linear mixed models were used to investgate the e ffects of natveness on four fundamental traits (leaf area, leaf dry mater content, specifc leaf area, and leaf nitrogen content), while the influence of growth-form, alttude, and site were employed simultaneously. We found signifcantly higher values of leaf areas and signifcantly lower values of specifc leaf areas for alien species if growth-form was included in the model as an additonal predictor.We showed that the trait-based approach of autochthony can apply to aquatc environments similar to terrestrial ones, and leaf traits have relevance in explaining aquatc plant ecology whether traits are combined with growth-forms as a fxed factor. Our results confrm the importance of traits related to compettve ability in the process of aquatc plant invasions. Alien aquatc plants can be characterized as species producing sof leaves faster. We argue that the functonal traits of alien aquatc plants are strongly growth-form dependent. Using the trait-based approach, we found reliable characteristcs of aquatc plants related to species invasions, which might be used, for example, in conservaton management.

Cím:	Sex-biased breeding dispersal is predicted by social environment in birds / Végvári Zsolt, Katona Gergely, Vági Balázs, Freckleton Robert P., Gaillard Jean-Michel, Székely Tamás, Liker, András

Megjegyzések:	Sex-biased dispersal is common in vertebrates, although the ecological and evolutionary causes of sex differences in dispersal are debated. Here, we investigate sex differences in both natal and breeding dispersal distances using a large dataset on birds including 86 species from 41 families. Using phylogenetic comparative analyses, we investigate whether sex-biased natal and breeding dispersal are associated with sexual selection, parental sex roles, adult sex ratio (ASR), or adult mortality. We show that neither the intensity of sexual selection, nor the extent of sex bias in parental care was associated with sex-biased natal or breeding dispersal. However, breeding dispersal was related to the social environment since male-biased ASRs were associated with female-biased breeding dispersal. Male-biased ASRs were associated with female-biased breeding dispersal. Sex bias in adult mortality was not consistently related to sex-biased breeding dispersal. These results may indicate that the rare sex has a stronger tendency to disperse in order to find new mating opportunities. Alternatively, higher mortality of the more dispersive sex could account for biased ASRs, although our results do not give a strong support to this explanation. Whichever is the case, our findings improve our understanding of the causes and consequences of sex-biased dispersal. Since the direction of causality is not yet known, we call for future studies to identify the causal relationships linking mortality, dispersal, and ASR.
